Hotpoint freezer FZA84 does not freeze ,high temperature light is on. when switched on the temperature comes down to about -12 C . does not come any lower but i hear a irregular hissing sound probably

Could you please recheck for the model number. R134A is a reference to the coolant used in the freezer mechanism.
Orange is often a reference to the 'Fast Freeze' function being turned On. Green is showing the freezer unit is at the correct temperature. Red is warning the freezer is Too warm. Some freezers are fitted with an 'Economy' function where the freezer can be run at a lower power level when not used regularly such as when on holiday.

Hi
Normally a fast freeze button is just that, it turns the compressor on permanently to freeze things down quickly.
I suspect that your run light is linked to the thermostat, and does not indicate that the freezer is turned off but that the temperature of the freezer is above the temperature set on the thermostat and the compressor is running to bring the temperature down. Once the temperature is at or below the thermostat temperature then the compressor will stop and the red light probably goes out, indicating the the freezer is at the right temperature.
It won't go out with the fast freeze on because to freeze food quickly the thermostat is by-passed and the compressor runs continuously.
Hope this helps.

Red light on for High Freezer Temperature Warning
or freezer not cooling, but fridge is and a lot of noise from compressor.
Also, fridge drain hole blocked, water in bottom of fridge.

This is a common fault in Hotpoint Fridge Freezers and can also happen if the door has been left open or has been a power cut.

1. Turn off fridge freezer, or at least turn down the freezer temp to minimum, though not ideal.
2. Open freezer door and remove all drawers.
3. Remove the back panel on the inside of the freezer. This is held in place with 4 screws, which might be 6mm hex head or star allen head. Pull the panel out.
4. Behind where the panel was, there is a cooling element for cooling, pipes, and below this a temperature sensor. If the fridge freezer is not switched off, then fold together a few layers of tinfoil and wrap around the sensor.
5. Use a hairdryer to slowly melt the ice. Melt it around areas where it appears to be hanging on, such as the corners of the cooling element or bolts, as well as any thin sections below the main block of ice around the cooling element, which will be supporting the main block. Use a plastic ice scraper to remove ice but not near pipes or sensor.
Warning: Be careful using electrics around water & melting ice & drips.
6. Below the cooling element, there is a drip channel & drain hole. If this hole is full of ice, pour a small amound of warm water down, leave for 10 seconds and pour a bit more until clear.
In the fridge, clear the drain hole in the same way.
Warning: Do not pour a lot of water down, as this water drains onto a tray above the hot compressor at the rear of the fridge freezer to be evaporated by the heat of the compressor and the tray will only hold a small amount.
7. When all ice is removed, dry all moisture. Put the shelves back. Close door. Turn on fridge freezer. Turn up the freezer temperature to your normal setting. Turn on fast freeze if available. After 1 hour, check with a thermometer. It should be cold enough after 1 or 2 hours.

Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

freezer thermostat needs replacing.

press the fast freeze button. Red light usually indicates the temperature has dropped below required level. Perhaps you have put some new stuff in to freeze

the temperature control is bad. when you push the fast freeze it bypasses the thermostat for 12-24 hours depending on which model you have. I am not able to find any parts information with the model number provided but you should be able to find a temperature control at any local appliance parts house or online thru any reputable supplier.

the

could be a leak. have it checked by a tech.
